Overweight? Congratulations!

Seen in this article from the New York Times about the rising number of diabetics in India:

"In perverse fashion, obesity and diabetes stand almost as joint totems of success.

Last year, for instance, the MW fast-food and ice cream restaurant in this city [Chennai, formerly Madras] proclaimed a special promotion: "Overweight? Congratulations." The limited-time deal afforded diners savings equal to 50 percent of their weight (in kilograms). The heaviest arrival lugged in 135 kilograms (297 pounds) and ate lustily at 67.5 percent off."
